How Underground Mining Works HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper uranium mines can reach 6,500 feet, or 2 kilometers.

Copper Mining and Processing Life Cycle of a Mine

Surface mining, which includes strip mining, openpit mining, and mountaintop removal, removes soil and rock from on top of the mineral deposit. It may begin as soon as the predevelopment steps are complete. Underground mining uses shafts and tunnels to access deeplyburied mineral deposits, while the overlying rock is left in place.
